yup. they are exactly that - just when you make a pair out of scrap silnylon they last longer <img src="/forums/images/graemlins/smile.gif" alt="" />
How often do you need to seam seal them? I heard the seams on VBL socks in particular need to be sealed often, or the moisture leaks out in your shoe.
I did when I made them, but I didn't have any silnet so it was kind of a more rubbery version of silicon cut with white gas. realisticly, a little moisture you really won't notice. most of it happily stews my feet like a wet suit. mind you I've made my pair and maybe had them out for 3 seasons, 2-3 trips per winter. I don't wear them in the summer or anything remotely like it. last time I used them they were still just fine.
